COMPOSITION FOR MARKING SHEEP AND OTHER ANIMALS.

' Specification of Letters latent.

Application filed February 24, 1911. Serial No. 610,585.

To all whom it may concern:

Be it known that we, ROBERT Wm'rEnEY COLLINSON and Cmrrom) .WHITELEY CoL- LINSON, subjects of the King of Great Britain, residing at Norwich and Bradford, England, respectively, have invented certain new and useful Improvements in Compositions for Marking Sheep and other Animals, of which the following is a specification.

This invent-ion relates to an improved soluble sheep mark, that is to say, an improved composition for marking sheep and similar animals for the purpose of identification.

The object of the invention is to provide a mark which will withstand climatic influences and weathering but which will still be easily removed when the wool or hair is washed prior to carding, combing and the like, by the wool being simply immersed-in the usual bath used in washing and submitted to the usual treatment.

A further object of the invention is to provide a mark or*composition which is noninflammable, which is very cheap to manufacture, which can be made up in a form ready for use or concentrated,'which when concentrated can be simply thinned down and which when too thick canalways be brought to its desired consistency by the addition of water.

In carrying out the present invention the basis of the mark consists of a fatty matter, grease or fatty acid and this is rendered soluble in and capable of being mixed with water by the addition to it or to the water with which it is to be mixed of a small amount of alkali (preferably ammonia) in matter must ofv course be added to the mark and for this purpose a coloring matter must be used that has no dyeing or tendering properties and one which will not have any properties which will tend to decompose or otherwise injuriously act either chemically or physically upon the other constituents of the sheep mark. If desired'carbonate of lime, earthy matter or other substances inert as regards the other constituents of the mixture or of the washing bath may be added to give the mixture greater covering power and more drying surface.

For the better comprehension of the invention the following example may be given: Wool fat 25 parts by weight, stearin 7% parts by weight, resin 2% arts by weight, ultra marine or lamp blac 40 parts by weight, 10% ammonia 5% parts by weight, water 430 parts by weight.

The method of preparation of a sheep mark formed with the above ingredients is PatentedMay so, 1911.

as followszMelt and mix the wool fat,

stearin and resin and pour the hot melted compound slowly with constant stirring into a homogeneous'mixt'ure of the ultra marine or'lamp' black, ammonia and one third the amount of water finally used maintainedat a temperature of 40 degrees centigrade. The resultlng compoundi allowed to d form a concentrated composition. I it be desired to form the composition in a condition ready for use the remainder of the water is stirred inafter the thorough incorporation of the, above mixture,.in either a cold or lukewarm state.

If desired the proportions of the fatty constituent, the-resin and (or), stearin maybe largely varied from those set forth above If it be-desired to obtain the sheep mark in a very concentrated form none of the water except such quantity as'is necessary to roduce the required alkaline solution nee beadded till just'before use. The term will sheep mark must be taken to include and 1. A soluble sheep mark consisting of woolfat, a small amount of alkali in solution,

stearin, resin, coloring matter and water substantially as described.

2. A sheep mark consisting of wool fat, stearin, resin, coloring agent, ammonia in 7 solution and water substantially as described.

In testimony whereof we affix our signatures 1n presence of witnesses.
